BACKGROUND OF THE INVENTION

Field of the Invention

[0002] The invention relates to a related field of a disinfectant, which can be made into a hypochlorous acid disinfectant or a hypochlorous acid tablet disinfectant, and relates to its production.

Description of the Prior Art

[0003] Chlorine-containing disinfectants such as sodium hypochlorite and calcium hypochlorite have been used for disinfection and sterilization for more than 100 years. Because it is easy to obtain for production, low in price, easy to use and has an accurate sterilization effect, it is the most commonly used sterilant in the current disinfection drug market, which is not only economical, but also can kill more than 90% of bacteria in a few minutes at normal temperature and neutral pH. The mechanism of its bactericidal action is the formation of hypochlorous acid in water, which can interact with the cell wall of bacteria, and invade the cells and oxidize with proteins or destroy the cell walls due to small molecule and being uncharged, thereby causing metabolic disorders and bacterial death. However, many studies have shown that the use of chlorine-based drugs in water is prone to produce chloroform, chlorine compounds and the like with organic substances, and hence has the problem of carcinogenesis, liver poisoning and kidney poisoning.

[0004] Further, chlorine-containing disinfectants have many disadvantages, such as corrosive to human skin mucous, unfriendly environment, and easy to rust the equipment; in addition, having strong irritating smell at high concentrations. It is reported that chlorine- and bromine-containing preparations have caused environmental pollution, which has attracted more and more attention Therefore, finding a disinfectant with good sterilizing properties without chemical residues has become a concern of government sectors and scientists.

[0005] For the percentage relationship between hypochlorous acid and pH value, please refer to Fig. 1, "Technology of Water Purification", co-authored by Tanbo Norihito and Ogasawara Hongichi, published by the Japan Gakuindo (1985). For the percentage of hypochlorous acid and pH value, please refer to the following instructions.

[0006] It is known to the public that in order to produce hypochlorous acid components, in Japan table salt (sodium chloride) is added to water, and electrolysis is performed through a diaphragm to generate; in anodic acid-forming water, a hypochlorous acid component (hypochlorous acid of 10-50 ppm with pH 2.5) is found; although hypochlorous acid is low concentration, it has a strong bactericidal effect. (Referring to Japan publication of patent application No. HO3-258392).

[0007] Thereafter, some Japanese companies used hydrochloric acid and water for electrolysis to produce slightly acidic hypochlorous water (hypochlorous acid of 10 to 30 ppm with pH 5 to 6.5); around 1990, Tatsuo Okazaki of OMC (Okazaki Manufacture Company) Japan used patented electrolytic equipment (Patent Publication 1993 No. 5-237478) to make a patented electrolyte by a fixed proportion of hydrochloric acid and table salt (sodium chloride) (Japan patent application No. 249755) and used non-diaphragm electrolysis to generate hypochlorous acid water which is named "Super Micro-softened Acidified Water" with a pH value of 4 to 7.0 and a concentration of hypochlorous acid of 50 to 80ppm. After the invention was launched on the market, it was introduced by major Japanese beer and beverage companies, dental clinics of the National Hospital, etc., opening a novel era of the hypochlorous acid application.

[0008] In 1998, Tatsuo Okazaki again invented a novel technology, in which a mixing machine of sodium hypochlorite and hydrochloric acid solution is used to produce hypochlorous acid sterilizing water with a high concentration of 50ppm to 200ppm. This technology eliminates the need to use electrolysis to produce high-concentration hypochlorous acid sterilizing water. Japan O Company also improved the storage structure of the sodium hypochlorite tank and the hydrochloric acid tank used by the above machine to apply for an improved patent. Please refers to Japanese Utility Model Registration No. 3085356 in 2002.

[0009] In 2006, Tatsuo Okazaki et al. reinvented a novel technology, i.e., a machine that uses sodium hypochlorite solution or sodium chlorite solution, and mix with carbonated gas to produce hypochlorous acid sterilizing water. it has a patent registered in Japan and China (Japanese Patent Application No. 2005-349382, China Publication No. CN101124169A). In this technology, dissolved carbon dioxide gas is used to produce carbonated water with an acidic pH, which is added to an aqueous solution of sodium hypochlorite or an aqueous solution of sodium chlorite to produce the hypochlorous acid sterilizing water having a pH value of 4.0 to 6.5, a slightly acidic. - The claims include adding an acid other than carbonic acid to sodium hypochlorite aqueous solution or sodium chlorite aqueous solution (note: please refer to claim 5 of the Chinese patent) to generate hypochlorous acid sterilizing water. This technology mixes sodium hypochlorite with basic pH and water with an acidic carbonated gas to generate hypochlorous acid with a stable pH of 4.0 to 6.5, wherein the hypochlorous acid has a concentration of 50ppm, 100ppm, 200ppm etc. (note: adjustable). The hypochlorous acid is slightly acidic with a pH of about 4.0 to 6.5 and has high stability. It can be used in various industries for sterilization, shorten sterilization time, be safe for people, and be friendly to the environment.

[0010] After the prior novel technology of hypochlorous acid is developed, the generated hypochlorous acid thereby has a concentration that is higher than the same produced by the electrolytic principle, and has a stronger sterilization. It has been widely used in Japan's major beer, beverage factories, food, restaurants, hotels, or national hospitals, dental clinics, aquaculture, livestock industry, aquatic industry, etc., and has been used in various industries for many years. Uni-President, King Car Group, Kinmen Kaoliang Liquor Inc., 7-11 and McDonald's Large Cut Vegetable Factories in Taiwan have used this technology for many years.

[0011] Chlorine compounds are the most commonly used fungicides, the reaction in water is the same as that of liquid chlorine and sodium hypochlorite solution (commonly known as bleach water); the conversion of chlorine content is expressed as "effective chlorine". and then chlorine (powder) is added to water to produce a chemical reaction, wherein the main dissociation produces hypochlorous acid (HCLO), hypochlorite ion (CLO-) and chloride ion (CL-). The chloride ion is the same as the main component of chloride ion in seawater, which have no sterilization effect. Hypochlorous acid (HCLO) and hypochlorite ion (CLO-) have a sterilization effect and are called "effective free chlorine".

[0012] However, hypochlorous acid (HCLO) and hypochlorite ion (CLO-) will vary greatly with changes in pH. Chlorine powder or sodium hypochlorite solution dissolved in water will generate hypochlorous acid (HCLO) and hypochlorite ion (CLO-). Although hypochlorous acid (HCLO) and hypochlorite ion (CLO-) are both effective free chlorines, the sterilization of hypochlorous acid (HCLO) is 80 times that of hypochlorite ion (CLO-). (See Fig. 2, U.S. EPA , partially added, "Water Purification Technology" published in Japan)

[0013] Since the chlorine powder or sodium hypochlorite solution has a pH that is alkaline after being dissolved in water, the hypochlorous acid group ion (CLO-) with weak sterilization dominates though some of the components are dissociated into the hypochlorous acid (HCLO) with strong sterilization . (See Fig. 1) In order to produce 100% hypochlorous acid with stable and powerful sterilization ingredients, as shown in Fig. 1, hypochlorous acid and hypochlorous acid group ions are 100% and stable hypochlorous acid when the pH is 4 ∼ 6.5, which is the main theoretical basis of the present invention.

[0014] The patent application of this novel invention is to apply for a novel chlorine powder (dichloroisocyanuric acid, sodium salt or trichloroisocyanuric acid), which is more stable and after than conventional novel chlorine powder because the composition containing chlorine compounds has been stabilized and treated, the chlorine powder ingredient is more stable and safer than traditional chlorine powder. The novel type of chlorine powder (dichloroisocyanuric acid, sodium salt, or trichloroisocyanuric acid) is added to water to dissociate the components of the chlorine compounds contained in it to produce hypochlorous acid (HCLO) and hypochlorous acid group ion (CLO-), which are alkaline in pH; in addition, the calculated proportion of sodium dihydrogen phosphate (inorganic acid) or citric acid (organic acid) or pH acidic components or raw materials is used to make the novel hypochlorous acid agent dissolved in water, so that a stable hypochlorous acid with high concentration is produced in slightly acidic water with pH value of 4 to 6.5 The hypochlorous acid product of this novel invention patent has strong sterilization effects and can conduct quick and powerful sterilization . It is safe for people, and friendly to the environment while being widely used in the disinfection and sterilization of various industries in the future. This novel type of hypochlorous acid agent will also gradually replace the traditionally-used chlorine powder or chlorine gas, or the traditional disinfectants such as sodium hypochlorite solution or calcium hypochlorite. It will be more widely used in various industries for disinfection and sterilization, and provide safer, more effective and more environmentally friendly sterilization method, which will benefit national health and environmental welfare.

[0015] The development of the novel hypochlorous acid agent of this application does not require the traditional use of electrolytic equipment to produce hypochlorous acid, and there is no need to plastic bucket (tank) to transport sodium hypochlorite solution, which greatly saves transportation costs or the use of plastic bucket containers. Users can add tap water or purified water into the product at anytime , anywhere, to produce hypochlorous acid with a concentration of 100ppm, 200ppm or higher for necessary disinfection or sterilization of vegetables and fruits, or for removing mildew or odor from the environment, bleaching, cleaning and sterilization of kitchen and bathroom, or for disinfection and demand of various industries.
